Biotechnology and mosses

[CMAXWELL at TRENTU.CA]

I came across a short article in Moore's book "Botany" on the possible use 
of genes from the moss Tortula ruralis, as Drought resistance enhancers in 
higher plants. There is no reference given for the work and I have been 
unable to find any papers on the topic. Can anyone out there point me in 
the right direction? It sounds like a very interesting topic to include in 
lectures.
Thanks
